2 Claims.

This invention relates to improvements in insect exterminators, and moreparticularly to a novel coating composition whichI may be applied to acardboard card or the like.

One of the objects of the invention is to Vprovide ar in sectexterminatdr for cockroaches and other insects which do not have lungs.

A further object is to supply a simple and ef icient means for theadministration of poison to such insects. l Another object is to furnisha coating composition containing a poisonous substance, and which Withthe foregoing objects outlined and with other objects in view which willappear as the description proceeds, the invention consists in the novelfeatures hereinafter described in detail, il lustrated in theaccompanying drawing and more particularly pointed out in the appendedclaims.

In thedrawing: Fig. 1 is a perspective view Iof the cordance with theinvention.

Fig. 2 is a sectional view of the same taken on card in acthe line 2--2of Fig. 1.

In accordance with the invention I propose a liquid exterminator whichcan be applied to a rectangular cardboard card or the like, and whichcomprises the following. ingredients.

(1) A mixture composed oi the following:

a. One-half gallon of water;

b. One quart of ordinary mucilage or glue:

c; One quart of glycerin; and

d. One pound of lampblack.

These ingredients are rst thoroughly mixed.

(2) A one gallon mixture of sorghum and simple syrup at a ratio of 1:3,respectively.

. (3) Eight ounces oLdisScLlvgd yellow phosphorus which is mixed withenoug'l'i'bbdislphide to dissolve it.

(4) One pound of dextrin.

In mixing the ingredients of the composition, No. 1 mixture is firstadrnixed with No. 2. After Nos. 1 and 2 have been thoroughly mixed, No.4 is stirred in. and finally the dissolved phosphorus is added and mixedwith the rest of the ingredients. This composition provides a two-gallonmixture, capable of being applied to a. card or other suitable base, andwhen it becomes dry, it adheres to the card or the like and lforms a 5smooth non-sticky coating thereon. The mixture can be applied to glass,wood, or any other suitable base as it is similar in fluidcharacteristics to ordinary coating compositions.

As shown in the drawing, a suitable card l of l0 cardboard or the likeis lpartially covered on both sides with the composition as indicated at2 and 3. This may be ac cpnipljsherinbilcdiplilllg; one end ptioifthecardinto the mixture,

permit Vsuch cards"'to"b` handled without the ngers coming' into contactwith 'the coating.

Furthermore the blank space on the cardmay be employed for advertisingdata or for directions, which may be printed thereon.

Ifthe composition is applied to cards, such cards may be wrapped inCellophane to preseve the composition until it is desired to use thecard.

- Instead of using black in the No. 1 mixture, it is obvious thai-,anyother coloring may be employed, but I have found that insects such ascockroaches and' waterwbugs are attited partilarlyby the black color.

It is also obvious that I may employ equivalents of the ingredientslisted, and of course, may mix the ingredients in various ways withoutadhering. strictly to the method outlined herein, although I prefer toemploy such method as it has been found effiicent in actual practice.

What I claim and desire -to secure by Letters Patent is: i

i 1. An insect exterminator consisting of a thin, stiff sheet-like,member having a large area of the `front and back-thereof completelycoated with a non-tacky composition comprising a colored insecticidehaving as constituents thereof insect food and yellow phosphorus, theuncoated portion o said member forming a handle to facilitate placementof the exterminator.

2. An insect exterminator consisting of a thin, stift sheet-like memberhaving a large area of the front and back thereof, its opposite edgesand one adjacent end, completely coated with a non-tacky compositioncomprising a colored insecticide having as constituents thereof insectfood and yellow phosphorus, the uncoated portion of said mem- -berforming a handlev to facilitate placement of the exterminator.
